laptop screen problem

My friend has a laptop running WinXp pro and when he started up the computer, the screen lights up but nothing shows up. Only weired colors shows, and  I think the screen is burned or defected somehow. The laptop has an adapter that connects to a regular monitor, so I hooked it up and then startup the computer. On the monitor everything was fine but not on the laptop screen. After when the computer did a system check, the monitor screen went blank. After that nothing shows up.

Could it be a hardware problem or software problem?

What you mean by system check ?

What happens now when you reboot your laptop again , connect the external monitor and then use the function key to switch to that monitor.. Make sure the hotkey utility in your OS is working fine to switch the video or just reboot the machine.

If it is going to show up on the external monitor , then definitely the laptop screen has gone bad .. Could be a  video card driver issue or video card issue if it is not going to show up on both the monitors

I mean when shutting down improperly and  a blue screen checks the harddrive for problems.

How olds the laptop?  its possible the screen has broken, have had screens go only after a couple of years (conviently after warrenty runs out).

Alternatively the driver for the monitor has become corupt.. Start it up with the monitor attached and go into device manager and check that the driver is installed correctly and working properly.  next check the graphics card

Hi speed_mst,

After reechecking If the system starts and that the only problem is regarding the laptop screen try the following:

first : Screen Resolution, (Click with right button mouse on Desktop, go to properties, go to settings separator page, on screen area select a low resolution something like 640x480) Click apply, ok and then restart with the laptop Screen.

If problem is not solved try the following:
Second: Driver (Go to Control Panel, System, Hardware Separator page, device manager, click twice above display adapters, select the opened driver and click delete, it asks if you are sure, click yes, then restart the computer with laptop Screen)

If none of this situation solves your problem, or the problem as been agravated (as it seems) when posting again please give us more details regarding, what laptop, drivers, and how exactly did that situation started.

Regards

the laptop is about 1.5 years old. I'll try that if I could login into windows.

If you can use another monitor and get into windows it might make sense to  download this tool, it'll do a check on the laptop and work out if there are any other problems. Get it here - http://www.pcdocrx.net/cgi-bin/view.cgi//index.html

Can you see the system POST screen? (counting RAM, manufacturer's logo, disk summary)
If not, and you have backlighting, I suspect the screen cable is bad or has become unseated or something like that. It may be a simple cable reseat that is the trick here, but if you're not cool about opening the thing up, you may want to talk to a repair shop about it.

I would try this.

Use the CRT monitor so you can see and boot into safe mode. from there once it's in safe mode switch back to the LCD screen using the correct buttons (usually function and a F key.) see if it displays anything there.

To me it sounds as if the laptop screen is shot or if it has a converter board that could be bad.

Speed, depends on what laptop you have but.

Near the screen itself in the botoom portion where your keyboard battery and hard drive etc is mounted but near the fold of the screen there should be a flat connector that looks like a piece of plastic with contacts on it.  This normally slots into a, well a slot.  It sounds like it "may" have been loose and then eventually went altogether and disconnected.  Check that first before you start going replacing the screen.

If its not that, then its your screen.  I would hope that on the laptop there should be a piece of removal plastic that will allow you to check this problem.  I hope its a dell and if it is then your ok to do that :)

good luck

Your joking me, well it must have been a problem with the connection to the screen to the Motherboard inside the laptop.  I would think that it's either not alighned properley or its a little loose.

I've had this problem before on a laptop..

What is was then was:

Screen died but view was accesable through plug and play monitor.  After leaving the lapotop for around a week turned it on and screen worked fine..  Then about a day or so later it died and has not come back since...

Basically what i'm saying is that its likely the screen is dieing

Hopefully i'm wrong and it continues to work.. But that is what i think will happen
